SHOE.

SPECIFICATION forming part of Letters Patent No. 502,973, dated August8, 1893.

Application filed June 9, 1893- Serial No. 477,045. (No model.)

To all whom it may concern: 7

Be it known that I, FRANCIS J 0s KING, a citizen of the United States,residing at Baltimore,in the State of Maryland, have invented certainnew and useful Improvements in Boots and Shoes, of which the followingis a specification. V

My invention relates to an improvementin shoes, and has for its objectto provide means for preventing the natural moisture of the foot frominj uriously affecting the leather of the shoe-upper and at the sametime provide the shoe with an absorbent for such moistnre-also toprovide means to prevent water leaking from the outside into the shoe.

In the drawings, Figure 1, is a perspective view of a shoe constructedin accordance with my invention and showing the toe cut oif to exhibitthe construction of the upper and the sole. Fig. 2, is a cross-sectionthrough the toe-part of the shoe. Fig. 3, is a plan view of thepermeable insole.

Referring to the drawings theletter, A, represents the usual leatherupper having the impervious lining, B, formed preferably of clothsaturated with a solution of india-rubber or of some other materialimpervious to the action of moisture. The usual cloth lining, C, ofdrilling or other material lies inside of the impervious lining. Saidimpervious lining extends entirely over the foot and as far up as thefoot has a close contact with the shoe. The three layers, to witz-theleather upper, the impervious lining, and the cloth lining,

all extend down and are secured at their lower edges between the insole,D, and the welt, 01. Outside the inner sole is the usual outer sole, E,and the cork layer, F, lies between the inner am t e outer so'eslyingnext the inner sole.

In welted shoes, such as herein described, and shownin the accompanyingdrawings, the insole must be made of leather sufficiently heavy andstiff to hold in place the upper of the shoe which is sewed to it:butleather which is sufficiently heavy for this purposeis not permeable andwill not permit the moist ure of the foot to pass through and beabsorbed by the cork layer, F. To obviate this difficulty, I provide theentire area of the inner sole with perforations, d, extending eutirelythroiigh the said insole, whereby direct communication is affordedbetween the inside of the shoe and the cork layer, and the moisture ofthe foot can be readily absorbed by the cork-layer. An impervious layer,G, lies between the outer sole and the cork layer, to prevent anymoisture leaking from the outside into the shoe.

The advantages of my shoe as above described are apparent;water cannotleak into the shoe from the outside, and the moisture exuded by the footcannot come into contact with the leather upper of the shoe. The latteris an important feature, because the said moisture is acidulated andcontinually acting on the leather upper of the shoe, finallydisintegrates it causing it to crack and become worthless. To get rid ofthe said moisture, the insole is made permeable as above described,whereby said moisture passing through the permeable insole, is absorbedby the cork-layer.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A shoe comprising an upper of leather; a water-prooflining adjoining the upper and covering the foot; an outer sole, E; acork layer, F; a layer of water-proof material G, between the outer soleand the cork-layer; a leather inner-sole, D, attached to the upper andhaving its lower surface in contact with the upper surface of thecork-layer, and provided with a number of perforations, d, so thatmoisture from the foot will pass through said perforations and beabsorbed by the cork layer, as described.

In testimony whereof Iaflix my signature in the presence of twowitnesses.

FRANCIS J OS KING.
